Our subsidiary Enel Generación El Chocón is a generator that operates the El Chocón and Arroyito hydroelectric plants. El Chocón is located on the River Limay which flows into the River Neuquén where the Arroyito plant is located and acts as a downstream compensator dike for El Chocón. Both plants are located in the region known as Comahue, formed by the Neuquén and Río Negro Provinces and the southern part of the Buenos Aires Province.
The hydroelectric complex has a total installed capacity of 1,328 MW. The El Chocón plant is one of the country's two largest water and energy reservoirs and has an installed capacity of 1,200 MW (artificial hydropower reservoir), while Arroyito has an installed capacity of 128 MW.
As a result of dispatch from the El Chocón reservoir, net generation by the El Chocón/ Arroyito complex reached 3,238 GWh at the end of fiscal year 2015, representing 2.3% of energy generation in the country as a whole.
